PSU 0-20V d.c variable
Project Board, pp272, 500 mA
Millimater d.c 0-100mA
Voltmeter dc 0-20V
Description:
Voltage of a resistor is directly proportional to its current. Resistors can show a tolerance which is stated on it.
- Experiment 2: NETWORKS
Experiment 2: NETWORKS
Objective:
To investigate what happens when resistors are interconnected in a circuit.
Apparatus:
PSU 0 - 20V d.c variable
Project Board, pp272, 500 mA
Milliameter d.c 0 - 100 mA
Voltmeter dc 0-20V
Description:
According to the Kirchhoff’s current law, the algebraic sum of all currents at any junction is zero. According to the Kirchhoff’s voltage law, in a closed circuit, the algebraic sum of the voltages around the circuit is zero.
- Experiment 3: Thevenin
Experiment 3: Thevenin
Objective:
To investigate the effects of more than one voltage source in a network.
Apparatus:
PSU 0-20V d.c variable
PSU 0-20V d.c variable
Project Board, pp272, 500 mA
